Shululsish has a large ethnic Vilani and mixed Vilani-Solomani population but has abandoned all but the more superficial aspects of traditional Vilani society. The government is notable as a participatory democracy on a high population world.

The government of Shululsish is a rarity: a participatory democracy on a high population world, made possible by high technology. Each of the world's 30 billion carries a terminal connected to the planetary computer; all eligible voters are polled regularly and important laws are enacted in this fashion. All executive officials are elected for one-month terms. This form of government places a heavy burden on the individual, and the average citizen spends an hour a day in government related activity, both voting and consulting computer net information services for the information needed to make a decision. This governmental system is made possible only because of the leisure time available to workers at this world's tech level; many citizens become government buffs, devoting most of their time to voting on issues and proposing new topics for discussion.

Non-canon: The most notorious sue of Terran biotechnological weaponry occurred on this world. The Terrans used weaponry of a biological warfare nature here. This is curious since the Terrans only employed these weapons once. During the 3rd Interstellar War the Vilani employed nuclear weapons against Terran civilian targets on the colony world of Fenris. In retaliation the Terrans deployed a viral weapon against the Vilani world Shululsish.

The virus proved to be more effective than the Terrans had envisioned; and within six weeks over 95% of Shululsish’s population of 500 million had died either from the virus or the social collapse that accompanied it. This one solitary attack was to have far reaching consequences. The Vilani were terrified by this new weapon; its effectiveness and their lack of any defence or counter measures were quite clear. However, the attack also had consequences within the Confederation. There was a huge public outcry against the use of these weapons, it was only the pressures of the war that prevented the entire biological warfare program from being abandoned all together.

However it was evident to the Confederation government that public opinion was very solidly against the use of these weapons and that there would be severe domestic consequences from any future deployment of biological weapons. As a result the Vilani and Terrans came to an informal understanding and neither side again deployed weapons of mass destruction against civilian targets.

Unfortunately the reluctance of the Terrans to employ their biological arsenal did not prevent the exposure of the Vilani to Terran diseases. It was inevitable that as the Terrans occupied a Vilani world, many of Earth’s hostile microbes would accompany them. As a result, the local Vilani population would be exposed to a plague of monumental proportions. It is a testimony to the Terrans dedication to their humanitarian roots (and their medical technologies) that, before the final collapse of the Ziru Sirka, on average only 5% to 10% of the local population died as a result of these plagues when the Terrans occupied a world. However with the final collapse, the Terrans occupied far more worlds than they could ever hope to deal with and the death toll from the plagues that swept through the former Ziru Sirka after the Interstellar Wars was far higher.
